Abstract

The invention discloses a five-axis NC machine tool calibration device and an operation method. The five-axis NC machine tool calibration device comprises a first calibration block and a second calibration block. The surfaces of the first calibration block are provided with a first calibration surface, a second calibration surface and a third calibration surface; the first calibration surface of the first calibration block is provided with a first round hole and a second round hole. The surface of the second calibration block is provided with a second locating pin and a second locating pin. The second calibration block, the first locating pin and the second locating pin are integrally designed. The five-axis NC machine tool calibration device conducts calibration on the zero point of a linear motion axis in the X-axis direction through the first calibration block and the second calibration block, conducts calibration on the zero point in the Y-axis direction and the zero point in the Z-axis direction through the same method and conducts calibration on the zero point of the rotation axis. Through accurate calibration, an NC machine tool can conduct machining more accurately. The problem that an existing machine tool calibration technology is not enough accurate in calibration and the machining precision of the NC machine tool is affected is solved.

Description

technical field [0001] The invention relates to the technical field of machine tool calibration, in particular to a five-axis numerically controlled machine tool calibration device and an operation method. Background technique [0002] Numerically controlled machine tools are well known and used in a wide variety of manufacturing industries. Today, these machines typically include a spindle or multi-axis rotary table that holds the workpiece with a milling cutter carried by a swivel head. The operation of this machine tool under computer control allows complex parts to be machined using a fully automated process. Such machine tools are increasingly being used with measuring probes to allow automatic inspection of cut parts. When a measurement cycle is required, the measurement probe is typically loaded into the spindle of the machine tool and then moved by the machine tool relative to the workpiece to allow measurement of multiple points on the surface of the workpiece. W...
